| Turn-around Time |
3-21 days |
| Interferences/Limitations |
- Material must be viable. Improper storage or shipping temperatures limit organism recovery.
- In the event of an outbreak, the procedure may be modified to screen for an additional set of organisms.
- Where a specific agent of an outbreak has been previously identified and there is a backlog of specimens, the procedure may be modified to screen only for a specified organism.
|
| Common Causes for Rejection |
- Insufficient quantity
- Unacceptable specimen type or source
- Improper shipping conditions
- Expired media or collection container
- Discrepancies between specimen label and submission form
- Incomplete or missing submission form.
|
| Additional Information |
- In the interest of public health, specimens will be accepted up to 30 days from the date of collection in an effort to identify the causative agent. The rate of recovery decreases over time.
- Specimens with positive CIDT results will be confirmed for the organism for which positive results were obtained. Please include results with submission.
- Routine stool culture includes screening for Salmonella sp., Shigella sp., Vibrio sp., Campylobacter sp., Yersinia sp., and shiga-toxin producing E. coli.
